## Overview

The SparkFun SEN-08942 Weather Measurement Kit equips professionals and enthusiasts with passive, highly reliable sensors to measure wind speed, direction, and rainfall. Featuring a 16-position wind vane, a cup anemometer calibrated to 1.492 MPH per rotation, and a tipping bucket rain gauge registering 0.28mm increments, this modular kit offers durable, easy-to-interpret data collection without active electronics. Perfect for building custom weather stations with professional-grade accuracy.

## Description

Whether you're an agriculturalist, a professional meteorologist or a weather hobbyist, building your own weather station can be a really rewarding project. When you're measuring weather, however, you need some pretty specialized sensors. This kit represents the three core components of weather measurement: wind speed, wind direction and rainfall. None of the sensors in this kit contain active electronics, instead they use sealed magnetic reed switches and magnets so you'll need to source a voltage to take any measurements. The positive side of this is that the sensors are easy to interpret: The rain gauge is a self-emptying bucket-type rain gauge which activates a momentary button closure for each 0.28mm; of rain that are collected. The anemometer (wind speed meter) encodes the wind speed by simply closing a switch which each rotation. A wind speed of 1.492 MPH produces a switch closure once per second. Finally, the wind vane reports wind direction as a voltage which is produced by the combination of resistors inside the sensor. When a voltage is supplied, the voltage returned can be translated to any of 16 possible positions.
